What we do

The Office of Sustainability (OOS) works with partners around the City to improve quality of life in all Philadelphia neighborhoods, reduce the City’s carbon emissions, and prepare Philadelphia for a hotter, wetter future. We organize around our theory of change, which outlines our understanding of the climate crisis and vision for the future.

OOS is responsible for implementing Greenworks Philadelphia, the City’s comprehensive sustainability plan, which is made up of eight visions:

  • Accessible food and drinking water
  • Healthy outdoor and indoor air
  • Clean and efficient energy
  • Climate-prepared and carbon-neutral communities
  • Quality natural resources
  • Accessible, affordable, and safe transportation
  • Zero Waste
  • Engaged students, stewards, and workers

    Rising Tide: The Crossroads Project Lecture

    February 23, 2022
    6:30 pm to 7:30 pm, 1 hour
    Rising Tide: The Crossroads Project, a multi-disciplinary live performance fusing original music with art, imagery, and science to address global sustainability and provide a path toward meaningful response. Through an original score by composer Laura Kaminsky, live musical performance by the Fry Street Quartet, lecture by physicist and educator Robert Davies, and imagery by visual artist Rebecca Allen and photographer Garth Lenz, Rising Tide unfolds in a series of vignettes juxtaposing the natural world from which we have emerged and the human world that has emerged from us. Grounded in science, elevated by art, and igniting response, The Crossroads Project confronts a planet under siege and a future in peril, inspiring audiences to change the course.

    This performance will include a lecture at the Academy of Natural Sciences on February 23, 2022 at 6:30pm.

    The performance in the Mandell Theater will take place on February 24, 2022 at 7pm.
